For those who have enjoyed Sister Catherine Clarke’s, Our Glorious Popes, an historical tribute to some of the more valiant Popes who graced the Chair of Peter over the centuries, this work, Gate of Heaven, is an equally worthy production from the pen of an historian gifted in the art of scholarly composition. Although this work abounds in numerous highlights drawn from ecclesiastical history and papal teaching its theme is more a song of gratitude to Our Savior Jesus Christ and to His Blessed Mother for so plentiful a redemption. The author exudes both her own joy in living the sacramental life within the Catholic Church, the one ark of salvation, and her holy indignation over the fact that liberal Catholic clergymen in the United States were teaching that one’s personal sincerity of conscience was an acceptable substitute for the one and only means of salvation given in, through, with and by Christ. Strong in her defense of Father Leonard Feeney, who championed the Catholic doctrine of "no salvation outside the Church," Sister Catherine demolishes all the ambiguous subterfuges that in her day (and far moreso today) were undermining the doctrinal clarity that in centuries past left no doubt as to the whereabouts of the only way of salvation. Anyone who truly loves the Faith and has Catholic zeal for souls would do well to give serious attention to this timely work, alarming as it is devotional.
